139119 divided by 87 
The aim is to understand the frequency of 87 in 139119.

Advancing to step 1:
When dividing 1 by 87, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 87

Step 2:
When dividing 13 by 87, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 87

Moving on to step 3:
The number 87 fits into 139 1 times, leaving a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 87 from 139 leaves us with 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 87

Let's proceed to step 4:
521 divided by 87 is 5 with a remainder of 86.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 435 from 521 to get 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 87

Let's proceed to step 5:
861 divided by 87 is 9 with a remainder of 78.
Put 9 as the next digit of the answer. 
Result so far: 159.0
If we subtract 783 from 861, we get 78.
Bring next digit (9) of the dividend behind the 78 and repeat the process: 789 / 87

Let's proceed to step 6:
87 goes into 789 9 times with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 1599.0
Deduct 783 from 789 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
The number 87 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 1599.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
When dividing 600 by 87, we get 6 with a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 1599.06
Deduct 522 from 600 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 9:
If we divide 780 by 87, we get 8 and a remainder of 84.
The number 8 becomes the next digit in our result. 
Result so far: 1599.068
Subtracting 696 from 780 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 10:
When dividing 840 by 87, we get 9 with a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 1599.0689
Deduct 783 from 840 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 11:
If we divide 570 by 87, we get 6 and a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 1599.06896
The remainder is 48 after subtracting 522 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 12:
If we divide 480 by 87, we get 5 and a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 1599.068965
Deduct 435 from 480 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 13:
When dividing 450 by 87, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1599.0689655
If we take 435 away from 450, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 1599.0689655 with a balance of 1.5e-07.
